[Matte88]

I'd like to play MGS2 on Linux so I decided to install Linux version of PCSX2 emulator before using it with WIne...
So I added pcsx2 overlay

Would you like to merge these packages? [Yes/No]

The installation fails 'cause emerge can't install ps2emu-spu2null
I read emerge's output, but I cannot understand exactly what needs...

error: gtk/gtk.h: No such file or directory

did you try installing or reinstalling gtk?

It is masked for removal in Portage, guess why that is.

# Michael Sterrett <mr_bones_@gentoo.org> (14 Apr 2010)
# gtk+-1 is old and nasty.
# Start transitioning away from these packages.
# Read man 5 portage about package.unmask to unmask the package locally.

So... Here I am... Again...
Re-installed gtk from Entropy with

Code: Select all

equo install x11-libs/gtk+-1.2.10-r12 x11-libs/gtk+-2.22.1

After this, emerging games-emulation/pcsx2 gave me another error (this time with games-emulation/ps2emu-gsnull; games-emulation/ps2emu-spu2null is not - still - installed).
Hey, why I can't find x11-libs/gtk+-1.2.10-r12 in Portage?
Before posting here I tried re-installing gtk with Portage-> failed!

Code: Select all

checking cairo-pdf.h usability... no
checking cairo-pdf.h presence... no
checking for cairo-pdf.h... no
configure: error:
*** Can't find cairo-pdf.h. You must build Cairo with the pdf
*** backend enabled.


Googlin' around the www I found this discussion about Cairo and pdf USE flag (look @ 2nd an last post)
Now take a look at this

Code: Select all

[ebuild     U ] x11-libs/cairo-1.10.2-r1 [1.10.0-r3] USE="X opengl svg xcb (-aqua) -debug -directfb -doc (-drm) (-gallium) -lib32% (-openvg) -qt4 -static-libs" 23,007 kB [0=>1]


At this point I stopped (didn't installed Cairo from Portage yet): what should I do?
I am attaching the logs needed

If it's being dropped from portage, I would find alternative.

Gotcha!
